FIGURE 9.
The effect of Lir on pressure overload induced cardiac hypertrophy. Mice were subjected to TAC surgery and treated with Lir for 25 days. Statistical results of the HW/BW, HW/TL, and LW/BW ratios (n = 10) at 4 weeks after TAC (A). The gross heart, HE staining (B) and CSA (n = 100 cells per section) (C) at 4 weeks after TAC. RT-PCR analysis of hypertrophic markers including ANP, BNP, and β-MHC from the heart of the different groups (n = 9) (D). Echocardiography results at 4 weeks after TAC (E, n = 10). Pressure loop measurements of systolic (SBP) and diastolic blood pressure (DBP) in different groups (n = 10 mice/group, F). ∗P < 0.05, compared to the corresponding sham group; #P < 0.05, compared to the control-TAC group.
